' The object of this invention is the pro- .duction of a resinous material suitable for use in lacquers and the like. Thlsr'esinous material is produced b .the interaction of may be employed. To this mixture is added one one-hundredth of a molecular equivalent 16 of a water soluble basic metal compound which in one one-hundredth normal aqueous solution produces a hydrogen ion concentration havlng a pH'value of more than 7.1. For this purposean hydroxide of one of the 20 alkali or alkaline earth metals or a soluble carbonate or phosphate ma .be' employed.

Upon addition of the. cata y'st a vigorous reaction ensues. mixture may be held m a pressure vessel or :5 in a vessel equipped forjrapid cooling and reflux condensation. The roduct is a pale yellow resinous mass, (2 "(he molecular equivalent ofdiacetone alcohol is mixed with one one-hundredth of a molecular equivalent 39 of the above'named catalyst. This mixture During this reaction the Application filed September 14, 192 8. Serial No. 135,487.-

is placed in a veshel equipped with means r for cooling and reflux condensation. The three molecular e uivalents of formaldehyde as above described arerun into the diaoetone alcohol. The roduct obtained is identical 85 'with that obtalned bythe first method. For illustration of the rocess the following example is given. o 1160 grams of diacetone alcoholare added 0.4 grams of sodium hydroxide dissolved in .10 cc. of wa 40 ter. This mixture is placed in a flask surrounded by. a cooling bath and equipped with a reflux condenser. Into this mixture is-run' slowly 2250 rams of 40%. aqueous solution of formal ehyde. ture rises rapidly. The mass is then re-' -moved from the flask.

A resinous mass separates and the supernatant aqueous layer is removed; The resinous mass is heated to expel the water and Bo fuse the mass. This resin is soluble in esters,- and ketones.

Havin thus describedv the invention what, Iclai'rnlsr The resinous body formed by the interac- 55 tion of one molecule of diacetone alcohol and three molecules of formaldehyde-in the "Pr s ce of an alkali. 1
